The jurys still out on the product, hardware is sound.. if it were just an ordinary bug in the firmware it would have been stamped out and updated and done as a software issue like hundreds of other bugs. the problem is in this case it was a bug that could cause a chernobyl fucking meltdown and responsible for the ONE job cold card has to keep funds secure. The fact this was overlooked or the more recent speculation that it was done purposely as people don’t believe they could be this negligent, and yet it is where the anger should be focused.
